Absolute frequency measurements of the line and fine-structure interval in K
Ayan Banerjee, Vasant Natarajan
We report a value for the -line frequency of K with 0.25 ppb uncertainty. The frequency is measured using an evacuated ring-cavity resonator whose length is calibrated…
Precise measurements of UV atomic lines: Hyperfine structure and isotope shifts in the 398.8 nm line of Yb
Ayan Banerjee, Umakant D. Rapol, Dipankar Das +2
We demonstrate a technique for frequency measurements of UV transitions with sub-MHz precision. The frequency is measured using a ring-cavity resonator whose length is calibrated a…
Precise fine-structure and hyperfine-structure measurements in Rb
Ayan Banerjee, Dipankar Das, Vasant Natarajan
We demonstrate a new technique for measuring the absolute frequencies of atomic transitions. The technique uses a ring-cavity resonator whose length is calibrated using a reference…
Direct measurement of the fine-structure interval in alkali atoms using diode lasers
Ayan Banerjee, Umakant D. Rapol, Vasant Natarajan
We demonstrate a technique for directly measuring the fine-structure interval in alkali atoms using two frequency-stabilized diode lasers. Each laser has a linewidth of order 1 MHz…
High-accuracy wavemeter based on a stabilized diode laser
Ayan Banerjee, Umakant D. Rapol, Ajay Wasan +1
We have built a high-accuracy wavelength meter for tunable lasers using a scanning Michelson interferometer and a reference laser of known wavelength. The reference laser is a freq…
